Find the area of the trapezoid if the bases of the trapezoid are 15 cm, 18 cm, and h = 14 cm

A trapezoid is a quadrilateral in which one pair of opposite sides is parallel, and the sides are not equal to each other.

In order to find the area of a trapezoid, you need to multiply the half-sum of its bases by the height:

S = (a + b) / 2 h, where:

S is the area of the trapezoid;

a – smaller base;

b – larger base;

h is the height of the trapezoid.

S = (15 + 18) / 2 ∙ 14 = 33/2 ∙ 14 = 231 cm2.

Answer: the area of the trapezoid is 231 cm2.
